- halted 312M Mli Letters Patent No.- 103,179, dated May 17, 1870.

IMPROVEMEHT I1; STATION-INDICATOR FOR RAILROAD CARS.

The Schedule referred to in these Letters Patent and making part or thename and State of New York, have invented and made anew and usefulIrnprovementin Indicating Apparatus &c.; and the following is declaredto be a full, clear and exact description of the said invention.

The object of this invention is to present, in regsignals in railroad orother cars, orwherever required.

My invention relatesto a ratchet-belt, combined with a sliding pulla ndswinging pawl, whereby the belt of names, numbers, orsignals'mu'be'revolved or wound off one roller upon another roller withfacility.

' The distance between the names uponth'e belt is to be increased inproportion to the increased diametcr of the roll upon which the belt iswound.

In the drawings-- Figure 1 is a vertical section of the apparatus, and

Figure 2 is a plan illustrating the said improvement.

The'belt or curtain a, upon which the names, numbem, or signals areplaced, is mounted upon the rollers b and 0, within the case or box (I,and behind the opening 0, so that the successive signals can'be readilyexposed through the said opening e. These parts are to be of any desiredconstruction, and I remark that I apply the operative power to the axisof. the

roller ll, and a f| iotion-strap, f, applied to the roller c, serves todetain the said roller 0 sutficiently to prei'ent looseness oi the belta,- and this fi'iction-strap maybe adjusted by a screw.

'lheratchet-beltxh passes around the pulleys 'i i, and is made with a.series of triangular teeth attached upon the leather or other materialof the belt.-

Tbe shaft of one of the pulleys i is connected to the shaft of .thebelt-roller b by gear-wheels l m, and I rcmark that the relativeposition of these may be varied the names of stations, street, or other.

to suit the position of the pull relatively to the opening 0. I

The pull n is made with a spring or swinging pawl,

0, that engages the teeth of the ratchet-belt h and said pull isfittedto more in a case or slide, ,p, and is returned'toa normal position by aspring, q.

. This pull a can stand horizontally or vertically, but parallel withthe belt of ratchet-teeth h.

A toe, "r, at one side of the pull a, may be used to ring a bell, s; asthe apparatus is operated.

It will now be understood that this mechanism allows the attendant tomore the indicating-belt more or less,'hecause the pull can be drawnentirely out to the extreme of motion, or be moved partially, or asecond time, if required,'to adjust the indicating-belt; and a largeextent of motion can be given both to the ratchet-belt andtheindicating-belt, in consequence of the ratchet-bclt being parallel tothe movement of the ull. p Each car in a train of railway carriages canbe provided with one'of these indicators; and the same can be operatedseparately, or all of them be connected together, so as to'be changedwith one pull.

I prefer that the belt a shall be of a length to contain the names ofall the stations going and returning, so that the belt will be woundupon the roller b each complete trip. and then wound back by hand uponthe roller 0.

I claim as my invention- The ratchet-belt It, provided with triangularteeth,

in combination with the indicating-belt a, and pull 11,

carrying the pawl o, the parts being arranged and opcrating as and forthe purposes set forth.

Signed by me this 1st day of March, A. D. 1870.
